What's the compression supposed to be on an 03 cobra in psi? I'm getting a compression test on one I might buy and wanted to make sure nothing was out of whack. Thanks

Also, if the car had been pullied and damgaed and then put back to stock would it show up on the test?

 

please help

 

i think i read somewhere, and i'm not 100% sure but they were supposed to be around 175psi

 

it will vary slightly from car to car. just make sure the numbers for all cycls are pretty close to one another.

 

it varies from car to car and altitude/barometric psi. run compression on all 8 cylinder like stated and make sure no cylinders are more then 20% apart, ford says even more then 20% is in specs but i prefer to use 20%
